![]() This keyboard also follows the standard Qwerty keyboard of laptops so that you won’t have a hard time adjusting to it. Moreover, this device lets you do hand gestures that send a command to your phone like zooming in and out the screen, turning to the next page, etc. You can use it basically anywhere you feel like as long as it is a flat surface. You may use a smooth countertop, your office tabletop, or your study table. This device holds your phone at an angle where you can properly read it and then it projects a hologram keyboard in any flat surface. This hologram keyboard looks like it’s straight out of a sci-fi movie! It is a cord-less and Bluetooth powered hologram keyboard that lets you type on literally any flat surface! With this device, you can now convert your mobile phone into a make-shift laptop. Pixels of the display are aligned with the hologram from the user's vantage point.Hologram Keyboard Bluetooth and Cord-free To solve this, we measure the position of the user's eyes so that we can determine which Underlying display appear to the user to be on different planes. This presents a problem, however, because the hologram and The beginning of theįollowing video shows the user turning on the holographic trackpad using a circular trigger gesture.Īnother benefit of having the hologram on top of a display is that you can dynamically add active elements to the hologram by changing the display-forĮxample, highlighting a holographic button to give feedback when the user ‘touches’ it. Of the video you can see that the user is controlling the scrolling of a map application by using the holographic interface.īecause the hologram is transparent, it can also be adaptively turned on or off as needed simply by toggling the LED that illuminates it on or off. Through the film to the underlying display (lower half of the video) as well as the floating hologram. ![]() Because of the small optical bandwidth, we can see In this demonstation, we place the imaged holographic film on top of a display. Your browser does not support the video tag or the video format. Is an imaging process that captures the three dimensional information of an object so that it can be reconstructed optically simply by shining light on the Perspective 2D image of a virtual 3D object in reaction to a user’s changing position in 3D space relative to that object), a “true hologram” Unlike some current uses of the term “computer hologram” (which refer to a process of using a computer to dynamically render the correct Were dirty (such as on a shared touch interface in a public place during a pandemic), the user need not come into physical contact with the potentially dangerous hardware. For instance, if your hands are dirty (such as when cooking in the kitchen), a touch will not dirty the button. Sensitive keyboard, and we used depth-sensing systems, such as stereo cameras, to determine when the user “touched” the hologram.Īn additional benefit of such illusory touch-sensitive buttons is that they are actually touch-free, this protecting both the user and the hardware from situations where oneĬan harm the other. In this project, we explored using holograms as a floating visual indicator, which we integrated with a touch-sensitive display and with a force. Secondly, we must measure when and how the user has interacted with the Give the user a visual indication of where in that 3D space the virtual trackpad is positioned. What if we could “place” a trackpad (or other UI element) in the 3D volume above a keyboard? To do this, we need to solve a couple of problems. Keyboard quickly fills up a small mobile keyboard, leaving little room for other UI elements such as a trackpad. Attempting to maintain those dimensions with the typical set of keys on a comnputer Keyboard, keys are of a standard size and spacing that users are already accustomed to. The ability to make use of vertical space would be particularly helpful on devices with limited surfaces, such as a tablet with a small keyboard attached. Project Helipad explores extending these interfaces to the full three-dimensional volumeĪccessible to the user, which provides more space for UI elements. Typical user interfaces in use today, especially touch interfaces, exist on two-dimensional displays or physical surfaces such as a computer monitor Schematic of the Project Helipad demonstrators discussed in this article
